Also performed as part of the mating dance several dives in the water in high altitude climbing and dive at full speed, make a bow and repeat it several times. This attracts females they may not be interested. After mating, the male will seek out other females and she will be working on a nest with moss, cotton spider web, where the two eggs deposited will empollará for two days and up to 3 weeks.

They usually mate between April and June, when the males chase the females, beat them and bite their paws. Appropriate mating, the male stands on the female, based on its hind legs and shows a series of amazing high-pitched noises

    Turtles: delayed fertilization

    A striking turtles process is called Amphigonia retardata, which is the ability of females to store sperm inside and fertilize eggs laid until three years later. To deposit eggs digs a deep well with its hind legs up to 12cm. They lay 2-12 eggs. The eggs of these reptiles contain a lot of calcium so they are especially tough. Incubation lasts about 2 months. Hatch from August to October. The turtles used to come out with a sharp bump on the nose and allows them to break the shell. This process takes about 2 days. Life expectancy is about 100 years.

    Bees necessary for human life

    Bees are animals that pass through several stages of development in which they can be seen very well mutate: egg, larva, pupa and adult. For bees cycle begins when the queen, who holds more than 5 million sperm, lays its eggs in the cells of a honeycomb. They can lay eggs lifetime and up to 2000 per day during the spring, amount wane with aging queen. The eggs, about 1 mm long, hatch after 3 days. Those were fertilized be worker bees and drones will be unfertilized or male bees. These larvae do not have wings, legs and eyes. There are responsible for feeding the larvae with pollen and honey bees. About 6 days after spin cocoons where they are located about ten days, after leaving converted into adult bees.

    Sunflower, a source of alternative energy

    The sunflower is one plant that is characterized by its peculiar way of always oriented towards the sun.

It usually lives in rivers and feeds on small fish. It has an incredible ear for orientation perfectly.

    Platypus, one of the longest-lived animals

    To reproduce, the female constructs a burrow digging a space 40cm deep and up to 6 meters long. In the end the eggs on the nest made of leaves and aquatic weeds are located. Covers the ground using its input queue and proceeds to start. Eggs usually two, of fairly soft structure and carrying two weeks incubation. When the young are born, they get into a kind of skin fold, which works like a sack where breast milk to feed is also deposited. The platypus has a long life expectancy in round 30.
